Answer:
0.0825
Step-by-step explanation:
1/4x1/3=0.0825
Answer:
Step-by-step explanation:
Well, the first one is 2/40=1/20. The 2nd one is 1/39. You multiply these to get 1/780.
C=2(3.14)(radius)
c=2(3.14)(250)
c= 1570
The arrangement of mother's eye level, ground level and playground forms a right angles triangle.
The legs of this triangle are 12.6 m (eye level to ground) and 20 m (building to playground).
Using trigonometry and assuming the depression angle is Ф;
tan Ф = 20/12.6 = 1.5873
Ф = tan ^-1(1.5873) = 57.78°
